HERMANN BAHLSEN, OF HANOVER, GERMANY.

BOX-OPENER.

VApplication led August 13, 1912. Serial No. 714,772.-

To all whom t may concern.'

Be it known that I, HERMANN BAHIsEN, subject of the German Emperor, residing at 352 Podbielskistrasse, Hanover, Germany, have invented certain new and useful Improvements in Box-Openers, of which the following is a specication.

The invention relates to an arrangement for tearing off the wrapper of. prismatic cardboard or similar packages by means of the cover.l

The novel feature consists in providing an incision directly beneath the edge of t-he lid in the flap which is located behind the front side, which is providedwith a known notch for the purpose of being able to grip ghe lid without having to bend back the In the accompanying drawing an illustrative embodiment of the invention is shown, in which- Figure 1 is a perspective view of the closed box without the wrapper, Fig. 2 is a perspective view of the box when open, with the wrapper, Fig. 3 is a section through the gripping notch on the line A-B of Fig. 1 on an enlarged scale.

a is the cardboard box, and b is the wrapper which forms a tightly tting cover. The front of the cardboard box is provided in a known manner with a notch o and behind the frontf the box is the Hap 0,2 of the lid a1. This flap a2 is, according to the invention, provided with an incision f directly beneath the front edge of the lid.

This incision extendsto nearly the end of the flap, and at both ends of this incision there are two arc shaped downwardly extending incisions fl, forming a tongue which may be bent inwardly and downwardly. On account of the incision f, after piercing the wrapper bat the notch c with the finger, it is-possible to engage the under part of the lid and by raising the latter to tear the wrapper open. It is ossible with this ar. rangement to place t e 1in r underneath the lid without having to nd back the whole ap, which is particularly diicult with filled boxes.

What I claim as new and desire to secure by Letters Patent is as follows:

1. A box provided with a movable lid, said lid havin a fiap adapted to lie behind the front w'al of the box when the lid is closed, the front wall havin a notch formed inits upper edge and said ap having a slit.

vided with a tongue adapted to re 'ster with said notch Awhen the lid is close whereby the finger may be passed through said notch to move said tongue inward to permit the ngerto pass through the flap and enga e the under surface of said lid without ben ing back said flap.

3. A box provided with a movable 11d, said lid havin a ap adapted to 4lie behind the front wal of the box when thelid is closed, the front wall having a notch formed in its upper edge and said flap belng provided with an inwardly and downwardly bendable tongue adapted to register with said notch when the lid is closed whereby the finger may be passed through said jnotch to move said tongue inward to permit the finger to pass through the flap and engage the under surface of said lid without bendin back said flap.

, n testimony whereof I have hereunto s et my hand in presence of two subscribing witnesses.
